This sounds like a business decision (good) so the answer depends on the real cost of keeping the page updated (cost of staff time, cost of obtaining the information on the page etc) compared with the value gained from the page(direct income generated from the page, financial value of the links it brings to the site as a whole, increase in brand awareness from having a popular page etc).
You then need to think about whether there are better ways to monetise the page (will people pay a subscription to see it? or to advertise on it?)
Your challenge is to attribute financial values to all these variables - then compare that with the alternative, if the page was removed. Without at least taking a view on that information it is not possible to make a balanced decision about whether to keep the page.
(Generally on balance I would keep a very popular page, for site and brand awareness reasons, unless it was clearly disproportionately expensive to keep.)
